Abstract

There is described an acoustic position detection system comprising one or more spaced acoustic signal generators located at predetermined relative positions and an object comprising: (i) a detector for detecting acoustic signals generated by the one or more acoustic signal generators and converting the detected acoustic signals into corresponding electrical signals; and (ii) means for processing the corresponding electrical signals to identify the respective times of arrival of the acoustic signals. The position of the object relative to the predetermined relative positions of said acoustic signal generators is determined using the identified times of arrival. Preferably, the acoustic signals output by the acoustic signal generators are spread spectrum electrical signals which reduces the noticeability of the acoustic signals to humans or animals.
